STOVEPIPE ANCHOR, FLUE THIMBLE, AND FLUE STOPP E R.

Application filed February 24, 1922. Serial No. 538,865.

To (1/ 7: 0m 1' i may cow-P r1? Be it known that l. T-ABHLTON B. SPARKS,a citizen at the United States, residing at Terre l-laute, in the countyof Vigo and State ot Indiana, have invented certain new and usefulLuprovements in a. Stovepipe Anchor. Flue Thimble, and. Fine Stopper, of

' which the ollowing a specification.

holding the stove pine thiinble in alace said g n L 7 means beingcapable of economical manutacture, reliable in operation and welladapted to the purpose for which it is designed.

"With the above and numerous other objects in view, the inventionrelates to certain novel. features otconstruction, and the combinationand arrangement oi parts will be hereinafter more "fully described andclaimed.

Referring to the drawings in detail it will be seen:

Figure 1. is a trout elevation of a flue stop showing the same in place,

Figure 2 is transverse section therethrough taken on the line 22 ofFigure 1 looking in the direction of the arrow,

Figures 3 and 4e are transverse sections taken on the lines 3 3 and 1iof Figure 2 looking in the direction of the arrows,

Figure 5 is a view similar to Figure 2 showing an elbow substituted torthe fine stop,

l igure G is a transverse section taken therethrough on the line t36 o'tllignre 5 looking in the direction of the arrow,

Figure 7 is an elevation ot the elbow coupling device,

Figure 8 is a similar view taken at right angles to Figure 7, and

Figure 9 is an elevation of the flue stop.

Referring to the drawings in detail it will be seen that 1 designates astove pipe thimblc which is situated in the flue opening 2 and isprovideiii at its Front end with a right.

angularly extending annular flange 3 that is adapted to fit against theouter surface of the wall in which the flue opening 2 is situated. A barat is spanned transversely of the thimble 1 adjacent its rear end beingfixed to the pipe by means of the rivets 5 through the right angularlyextending apertured lips 6. This bar 4 is provided with a centralaperture through which extends the rod 7 so as to be rotatable therein.A stop block 8 provided on the rod 7 on one side of the bar 4 and a stoppin 9 is situated on the other side thereof so as to prevent sliding ofthe rod 7. The inner end ot'this bar is threaded while the outer endthereof is provided with an operating handie 11. Upon the threaded endot the rod 7 there mounted a nut 18 which is provided with a series ofspaced radially extending ears lt which are arranged in pairs so as topivotally receive therebetween the links 15 to which are connected theauxiliary arms 16 attached to the outer terminal of the main retainingarms 17. These main retaining arms 17 are fixed to the thimble 1adjacent its inner end and their outer ends extend so as to terminateadjacent the inside of the wall 1n which the flue opening 2 is provided.These terminals of the main arms 17 are provided with angular eXten--sions 18 that are adapted to engage the inside ot the wall as is shownto advantage in Figure 2 for holding the thimble 1 within the flueopening 2. From the construction thus far described it will be seen thatby rotating the rod 7 the nut 13 may be moved toward or away from thebar 4.. When this nut 13 is moved away from the bar 4, the terminals ofthe main arms 17 are forced away from each other so as to place theangular extensions 1.8 in engagement with the inner face of the wall inwhich is provided the flue. When it is desired to remove the thimble 1the nut 13 is moved toward the bar 1 thereby bringing the terminals ofthe main arms 17 toward each other and releasing the angular extensions18 from engagement with the wall whereby the thimble may be pulled outof the flue opening 2 as will be readily understood. 1

Intermediate the ends of the thimble 1 there are provided a plurality ofinwardly The flue stop 21 is provided with a cylindrical body portionbeing closed at one end by a plate 22 which extends beyond the peripheryof the cylindrical body portion of the stop forming a flange 23. Thisplate is provided with a grip member 24 so that the stop maybe moved inand out of the thimble 1. At the open end of the cylindrical body of thestop 21 I have provided a plurality of bayonet slots 25 which arearranged in pairs and are disposed in diametrically opposite relation toeach other for engagementwith the pins 20 and thus this stop 21 may beheld in fixed relation to the thimble 1 as will be readily understood.

When it is not desired to use the flue stop 21 but it is desired to usean elbow 26 so that a stove pipe may be attached thereto and, supportedthereby, I use a coupling member 27 which is constructed of: acylindrical body portion or thimble having bayonet slots 28 at one end.engageable' with the pins 20 in the same manner as was set forth inconjunction with the stop 21. and its slots 25. This coupling isprovided with. a semi-annular slit 29 adjacent its forward end so as toform jaw sections 30 which are slightly separated as at The terminals ofthese jaw sections are provided with brackets 32 having upstanding oroutwardly extending apertured members torreceiving the bolt 34 wherebythe jaws 30 may, be brought together by means of abut threaded on thebolt. In assembling the elbow in connection with the coupling thejaws-i0 are separated and. the elbow is inserted into the coupling as isillustrated in Figure 5. The nut 35 is then tightened on the bolt 34- soas to bring the jaws together, thereby clamping the coupling inengagement with the elbow 26 and holding the same firmly in place.

Having thus described my invention what I claim as new is 1. Incombination, a stove pipe thimble,

means associated with the thimble for en-' gaging a stove pipe, aplurality of resilient arms extending therefrom and terminating inangular extensions, a plurality of auxiliary arms atta hed at one end tothe terminals of the first mentioned arms, a bar extending transverselyof the thimble, a threaded rod rotatable in the bar, a nut on thethreads of said rod, and means for connecting the auxiliary arms to thenut.

2. In combination, a stove pipe thimble, means associated with thethiinble for engaging a stove pipe, at bar extending transversely of thethimblc and fixed thereto and provided with a centrally disposedaperture, a rod extending through said aperture so as to be rotatablymounted therein, means for preventing sliding of the rod, said rod provided with threads, a nut mounted. on said threads, a plurality of linksmounted on said.
